Given numbers are 407,978,999,653
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,978,999,653 is 2339316342.
Find LCM of 407,978,999,653 with Prime Factorization
| 3 | 407, 978, 999, 653 |
| 37 | 407, 326, 333, 653 |
| 11, 326, 9, 653 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 11 x 326 x 9 x 653 = 2339316342
Therefore, the lowest common multiple of 407,978,999,653 is 2339316342.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
407 x 978 x 999 x 653 = 259664113962
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
407 : 1, 11, 37, 407
978 : 1, 2, 3, 6, 163, 326, 489, 978
999 : 1, 3, 9, 27, 37, 111, 333, 999
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,978,999,653, is 1.
Now, the common factors can be found like this.
407:11x 37
978:2x 3x 163
999:3x 3x 3x 37
653:653
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 37 = 111
Therefore, the value for common factors is 111.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 259664113962/(1x111)
LCM = 259664113962/111
LCM = 2339316342
Thus, we can understand that the LCM of 407,978,999,653 is 2339316342.
